3 Equilibrium existence in a free and fair economy

In a free and fair economy, agents make decisions that affect their payoff and the payoffs of other agents. One natural question that therefore arises is whether an equilibrium exists. In this section, we first show that a free economy can be modeled as a strategic form game and use the notion of pure strategy Nash equilibrium [Nash, 1951] to capture incentives and rationality. Our main result is that a free and fair economy always has a pure strategy Nash equilibrium.
